How to take apart Acer Aspire 5820TG
5820TG是2010買的舊筆電。我在2013年底改用MacBook Pro Retina，是SSD，開機速度快，每當回頭再用到5820TG時，真的覺得慢到受不了，就很少用了。最近出借給別人，回來後系統怪怪的，於是用Acronis回復到2013年退役前，有做備份硬碟的image，Restore成功回復到2013年退役當時的系統。
接著，就是漫漫似無止境的Windows Update，還伴隨著一些狀況。首先就是Windows Update程式本身出現問題，檢查更新時，出現更新失敗的錯誤訊息，Google搜尋一下，到Microsoft下載Fix跑跑，就可以了。
要繼續Update之前，心想既然跑得慢，不如把一些程式移除，讓5820TG作文書和上網用就好了。於是開始移除大量的程式。這台硬碟有500G，被切成2個partition，各約240G左右。一個系統碟一個存資料，系統碟可是裝了快200多G。
幾個大的程式多達10多G的也有。Visual Studio VS 2008, VS 2010, VS 2012隨著寫程式的經歷，每版有都有裝。SQL server 2008, SQL server 2010，還有Microsoft Expression Studio都算大隻的。Matlab 2010, Matlab 2012，SPSS，Photoimpact X3, Dreamweaver 5.5，很多很多，其他..略。
雖然移除大量程式也要花很多時間，不過想要讓系統單純一點，也可以省卻一些需要Update的時間，再做個備份image放著，可以再用個幾年。做著做著，竟然出現了Runtime error 216 XXXxxXXx的訊息，後面號碼沒記下。
起先認為可能是移除時有出錯，雖然到此時已經斷斷續續花了二天了，還是含淚重新回復原來的備份。打算重頭再來一次。只是，怪怪....，回復原來的備份後，一開機(不可能瞬間中毒吧)，竟然還是同樣Runtime error 216 XXXxxXXx的訊息，而且Runtime error 216後就沒有畫面，連桌面都無法正常開啟，什麼事也不能做。
我直覺認為是硬碟的問題。因為我一直有付費買Trend的防毒，也不會開疑似有問題的信件和網站，況且以前一直也都是正常的，所以不認為是中毒。(PS：嘿嘿，不是都不上網玩啦。而是，我有一台專門亂逛亂搞的桌機，電腦區分正經和非正經用途，以免耽誤重要的東西和事務)。既然硬碟掛了，那就順便換成SSD好了，早就想換了，現在正便宜。(2016-7-18)買了下面這顆，算便宜。這容量的SSD還是萬把塊時，我就想換了，好不容易撐到他變成二千元不到。原本還擔心裝不下或不相容的問題都沒有碰到，換上後，順利再用Acronis回復原來的系統碟。
只是，怪怪....又來了，竟然還是Runtime error 216 XXXxxXXx的訊息。這時我想不妙，硬碟沒壞(多花錢了)是記憶體壞了，一隻原裝2G，一支加裝的2G，逐一拆掉，一支一支獨立測試，都正常。這下更不妙，如是是其他硬體故障，我才不想再花錢送修，那SSD真的是多餘的了，又多花錢了。
最後只剩一個選擇，抱著姑且一試的心情，找出Recovery CD(原廠沒附，當時得自己燒出來)共3片，重新安裝回出廠的狀態。咦，竟然OK。這樣也好，趁7/29日，Windows 10免費更新的最後期限，趕緊升級到windows 10。原來，5820TG沒打算升級windows 10，是想保留本來Windows 7上安裝的程式。最後，無心插柳升級到Windows 10，可以再用個幾年。
只是，還是不確定，問題是出在哪裡？難道2013年時的image就有中毒？!
要買SSD前怕不能裝，先拆開來看看。所以留下這篇轉貼文，【轉】Acer Aspire 5820TG 拆解。也給需要的人參考。
In this post I explain how to take apart an Acer Aspire 5820T series laptop.
I will take it apart down to the motherboard.
Here are major disassembly steps:
STEP 1-5: Accessing both memory modules, hard drive, DVD drive.
STEP 6-12: Removing the keyboard.
STEP 13-18: Removing the top cover (palmrest) assembly.
STEP 19-23: Removing the motherboard.
STEP 24-25: Accessing the cooling fan, CMOS battery and DC power jack harness.
If you would like to replace the LCD screen, you should check this LCD replacement guide
. It should be very similar.Make sure the computer is turned off before you start disassembly.
STEP 1.
Remove the battery.
STEP 2.
Remove eight screws securing the bottom cover.
Lift up and remove the cover.
STEP 3.
Under the bottom cover you can access the following laptop components:
– both memory modules.
– CMOS battery.
– hard drive.
– wireless card.
Acer Aspire 5820T can take up to 8GB RAM maximum. You can install up to 4GB RAM module into each slot.
STEP 4.
Slide the hard drive to the left to disconnect it from the motherboard.
Lift up and remove the hard drive.
Acer Aspire 5820T has a regular 2.5″ SATA hard drive installed. It can be replaced with any other large capacity 2.5″ SATA hard drive or 2.5″ SATA SSD.
STEP 5.
Slide the DVD drive to the left to disconnect it from the motherboard.
Remove DVD drive.
NOTE: the DVD drive was secured by one of the screws we removed in the step 2.
STEP 6.
You’ll find six spring loaded locks on the upper side of the keyboard.
In order to remove the keyboard you’ll have to push all locks into the case and lift up the keyboard.
STEP 7.
Here’s how you do it.
Push one lock into the case with a small flathead screwdriver. At the same time lift up the keyboard a little bit.
When the keyboard lifted up it will not allow the lock to slide back into the locking position.
Do the same with all remaining locks.
STEP 8.
Lift up the upper side of the keyboard and remove it from the laptop base.
Be careful. The keyboard still connected to the motherboard.
Turn the keyboard upside down and place it on the palmrest.
STEP 9.
Now you can access the keyboard cable connector.
It’s necessary to unlock the connector and release the cable before removing the keyboard.
STEP 10.
Lift up the brown locking tab with your fingernail.
It will open up at a 90 degree angle.
The locking clip must stay attached to the white base.
STEP 11.
On this picture the same connector shown in the unlocked position.
Pull keyboard cable from the connector.
STEP 12.
Now you can remove the keyboard.
STEP 13.
Remove all screws from the bottom of the laptop.
STEP 14.
Remove all screws securing the top cover assembly.
Disconnect the following cables:
1. Speaker cable.
2. Power button board cable.
3. Touchpad cable.
4. Switch board cable.
Here’s how to disconnect the speaker cable.
It’s a regular male-female type of connector. Simply unplug the male part from the female part.
Do not pull by the wires. Disconnect it by the edges of the connector.
Disconnect three other cables the same way you disconnected the keyboard cables in steps 10-11.
Unlock the connector first by lifting up one side of the locking tab.
Pull the cable from the connector.
STEP 15.
Stat separating the top cover assembly from the base cover.
STEP 16.
If the top cover doesn’t separate, use a piece of plastic (I’m using a guitar pick).
Insert it between the top cover and bottom cover and slowly move along the side.
STEP 17.
Remove the top cover assembly.
STEP 18.
On the other side of the top cover assembly you can access the following laptop components:
– Switch board.
– Both speakers.
– Power button board.
– Touchpad.
STEP 19.
I’ll be removing the motherboard so it’s necessary to disconnect both antenna cables from the wireless card.
STEP 20.
Also, unplug the DC jack connector from the motherboard.
This connector located under the bottom cover which we removed in the step 2.
STEP 21.
Remove one screw securing the motherboard.
Disconnect the following cables from the motherboard:
1. Microphone cable.
2. Video cable.
3. USB board cable.
Here’s how you unplug the video cable connector.
Just lift it up by the black belt attached to the connector.
STEP 22.
Start removing the motherboard from the base as it shown on the following picture.
STEP 23.
The motherboard has been removed.
STEP 24.
On the other side of the motherboard you’ll get access to the cooling fan and CMOS battery.
By the way, in Acer Aspire 5820T the CMOS battery IS NOT soldered to the motherboard. It can be unplugged and replaced.
STEP 25.
The DC jack harness is running under the right hinge mounting bracket.
There shouldn’t be a problem to remove the DC jack harness and replace it with a new one if need.
